The main types of solar panels are monocrystalline silicon, polysilicon, as well as amorphous silicon, if it is weak light, the election which is good? Amorphous silicon solar panel manufacturers to give you a detailed analysis:
Amorphous silicon: small size, long current is relatively small, poor direction (no direct point to the light source.) Crystal arrangement disorder, is a low purity products.
Monocrystalline silicon: large volume, long current is also large (very suitable for power generation !!), poor direction (must point to the light source.) Crystal arrangement orderly, is a high purity products.
Polysilicon: medium volume, long current is also smaller than the single crystal silicon, good direction (no direct point to the light source.) Crystal arrangement disorder, is the purity of the general product.
If it is power generation, you must buy monocrystalline silicon.
